The Near Infra-Red Spectrum of Water Vapor Part II. The Parallel Bands $ν_{3}$ , $ν_{1} + ν_{3} \cdot ν_{2} + ν_{3}$ and the Perpendicular Band $ν_{1}$

An analysis of the rotational structure of the three "parallel" type bands,

ν_{3}

ν_{1} + ν_{3}

, and

ν_{2} + ν_{3}

and the "perpendicular" type band

ν_{1}

has been carried out. The data lead to the following effective values of

A

B

, and

C

: (

A = \frac{h}{8 π^{2} I_{a}}, B = \frac{h}{8 π^{2} I_{b}}, C = \frac{h}{8 π^{2} I_{c}}

);

A (ν_{1}) = 27.26

B (ν_{1}) = 14.28

C (ν_{1}) = 9.17

A (ν_{3}) = 26.50

B (ν_{3}) = 14.40
